AT&T Watson is a voice recognition tool that transcribes spoken words into text on the fly. AT&T has officially releases the Voice Recognition Technology & Speech API for developers. Developers can now integrate this speech recognition technology into their own innovative mobile apps. Using this voice recognition API, app developers can easily utilize the AT&T Watson speech API to bring their innovative mobile app ideas to life. Developers simply need to send the audio to AT&T and its voice recognition engine will send it back to the app as text format. Researchers plan on continuing to develop APIs for specific categories to ensure the best use of the technology. AT&T Voice Recognition API website.
